JOINTED IRON FOR VEHICLE-SEATS.

SPECIFICATION forming part of Letters Patent No. 449,419, dated March 31, 1891. Application filed December 24, 1890. Serial No. 375,671. (No model.

To aZZ whom it may concern.-

Be it known that we, GEORGE H. HUTTON and GEORGE H. HUTTON, J12, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new an d useful Improvements in Jointed Irons for the Lazy-Backs of Vehicle-Seats, of which the following is a specification.

This invention relates to jointed irons for the lazy-backs of j ump-seats for vehicles, and has for its object to provide irons by whose adjustment the lazy-back can be turned forward upon the seat and turned backward to a horizontal position to serve as a seat.

To this end the invention consists in a double-jointed iron for lazy-backs, which comprises two sections secured to the seat and back, respectively, and connected by two joints, one of which is brought into play when turning the lazy-back to its forward position and the other when turning it to its backward position.

The invention is illustrated in the accompanying drawings, in which two forms of our device are shown.

Figure 1 represents a side view of a jumpto make up the iron; Figs. 10, 11, and 12, cor-.

responding views to Figs. 1, 2, and 3, representing another form of our improved iron; Fig. 13, a side view of this latter form of iron, showing the position to which the parts are brought preparatory to shifting the lazy-back to its turned-baelnvard position; and Fig. 14, a rear View of the section of the iron for attachment to the seat.

The letter D designates the seat, and F the lazy-back, and it might be well to state, primarily, that the various positions of these parts with relation to the front seat and vehiole-body are clearly shown and described in our companion application for a patent of even date, and reference is made to such application for a full understanding of the general arrangement of parts in a convertible vehicle.

The jointed iron comprises two sections 9 h. One of these sections 9 is for attachment to the seat D and projects up from the back edge thereof and forms a rigid standard, and may incline slightly to the rear, as shown. The other section It is for attachment to the back F, and in securing it to the first-named section two joints are employed. When the back is turned forward, one joint i is brought into play, and when it is turned backward the other joint 2" is brought into play.

In the form shown in Figs. 1, 2, 3, 4, 5, 6,7, 8, and 9 these two joints are constructed and arranged as follows: The seat section or standard g has at its upper end a rigid rearward-projecting joint-bar p, and the backsection has a corresponding rigid joint-arm 07.. These two rearward projecting joint parts p n lap across each other, and the two pins forming the pivots of the joints 2' e" pass through the said joint parts. IVe prefer to form the joint-bar of the seat-section double, comprising two members which fit on opposite sides of the joint-arm n of the back-seetion 71.. One pivot-pin 8 forms the front joint i, while the other 5' passes through the rearward ends of the said parts 12 a and forms the rear joint 2''. In the present instance the said pins are both removable, and may consist of thumb-screws, as shown, the screw-thread being only 011 the extremity.

It will be observed that with both the pivotpins in place the two joints will be held rigid and will be enabled to resist pressure applied against the back F when the latter is in an upright position. To adjust the back in the turned-forward position, the rear joint-pin s is taken out and the said back turned forward on the front pivot 8. To adjust it in the turned-backward position, the front pin 5 is taken out and the said back turned backward on the rear pivot s.

In the form shown in Figs. 10, ll, 12, 13, and 14 the two joints of the iron are constructed and arranged as follows: The seat ward the rear stop-shoulder 70 and has an upper angular corner Z and a rear face Z, that is curved concentric with the pivot s. The back-section h has at its lower end a rearwardprojecting joint-arm n of the samethickness as the joint-ear 70 on the other section. This j ointarm has a hook or beak 0 of shape to correspond with the rear face Z of the j oint-ear 76 of the other section, and the edge n of the j oint-arm, which is proximate to the top edge of the said ear, has a suitable shape to correspond therewith. A shortlink-bar 13 laps across the side of the j oint-ear 7c and the side of the j oint-arm n, and the pivot-pin which forms the j oint zl passes through the said link-bar and the joint-ear 7c and the pin of the joint 2" passes through the link-bar and the joint-arm n. We prefer to employ two link-bars 17, one at each side. \Vhen the back-section h is in an upright position, as in Fig, 10, the joint-arm edge at rests in contact with the top edge of the jointcar 76, and its hook or beak 0 is in contact with the rear face Z. When the parts are in this position, it will be seen that the backsection h cannot turn backward nor have any movement on its rear joint 11'. Thus this construction of parts serves to hold the two joints rigid when the back-section is in an upright position. The hook or beak 0, however, does not hinder the back-section h from turning forward on the front joint 2', as shown in Figs. 13 and 11. To adjust the back to an ordinary turned-forward position, it is only necessary to turn the lazy-back F on the front pivot i of the iron. The position which the two joints will then have is shown in Fig. 11. To adjust the back in the turned-backward position, first turn forward the lazy-back F on the front pivot 1' until the hook or beak 0 of the joint-arm n has passed the angular corner Z of the joint-ear 7c. Then the lazy-back may be pushed forward to draw the joint-arm n from between the links 19. The lazy-back can now be turned backward on the rear pivot 'L" to the position shown in Fig. 12. This latter construction is the same as that shown in our application filed December 24, 1890, Serial No. 37 5,67 0, and therein claimed. In this present The forward part of this joint-ear application we make no specific claim to the same.

It willbe seen that the objects in view can be readily and-conveniently attained with either form of double-jointed iron.

It is evident that changes may be made in the construction and arrangement of the several parts composing our invention, and therefore the invention is not limited to the construction shown.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. A double-jointed iron for the lazy-backs of vehicle-seats, comprising two sections secured to the back and seat, respectively, and connected by two joints, one of which is brought into play when turning the lazy-back to its forward posit-ion and the other when turning it to its backward position.

2. An iron for the lazy-backs of vehicleseats, comprising two sections h g, secured to the back and seat, respectively, with an end of one section proximate to an end of the other, and two joints it" between the two sections, one of said joints being at the front side of theiron and the other atthe rear-side, as set forth.

3. An iron for the lazy-backs of vehicleseats, comprising two sections h g, secured to the back and seat, respectively, with an end of one section proximate to an end of the other and one of said proximate ends having a rearward-projecting arm n and two joints 6 1" between the said proximate ends, the pivot of one of the joints passing through the said rearward-projecting arm, as set forth.

at. A double-jointed iron for the lazy-backs of vehicle-seats, comprising two sections secured to the back and seat, respectively, and each provided with a rearward-projecting joint-arm, the one lapping across the other and connected by two removable pivot-pins s s, substantially as and for the purpose described.

In testimony whereof we affix our signatures in the presence of two witnesses.
